Product Details

When language poses a barrier to typical administration, or where traditional intellectual assessment results would be questionable due to language-related difficulties, the WNV is appropriate for all individuals.

WNV is a valid tool for use with low incidence disorders such as cerebral palsy, aphasia, physically-/multiple-handicapped, and autism spectrum disorders.

Benefits

No need to pantomime of instructions.

Native language of the examinee is irrelevant to performance.

Deploy full battery or brief version of the tool according to need and offer help, when appropriate, with flexible standard administration.

Support Spanish-dominant examinees when no Spanish-speaking clinician or translator is available.

Meet current IDEA requirements.

Features

Both a Full Battery and Brief Version of WNV are available. The Full Battery includes the following subtests: Matrices, Objective Assembly, Coding, Recognition, Spatial Span, and Picture Arrangement. The Brief Version includes two subtests and yields a single ability score.

With supplemental directions in several languages, WNV is ideal for use in schools with individuals from multiple language backgrounds, including:
